If you want all-day music with real hybrid noise cancelling and a pocketable charging case, choose TOZO NC9; if you need a single-ear headset built for calls, driving and long work shifts, choose Atheewon Headset V5.4.
• TOZO NC9 – biggest strength: true hybrid active noise cancelling rated to a 45dB reduction depth, plus a 60-hour total playtime figure from the charging case.
• TOZO NC9 – biggest trade-off: it is a two-earbud in-ear set, so you always need the case nearby and you have to take an earbud out to talk to someone (or switch to Transparent Mode).
• Atheewon Headset V5.4 – biggest strength: a single-ear hook design with a physical mute button, a USB dongle for non-Bluetooth computers, and a 115-hour total playtime figure.
• Atheewon Headset V5.4 – biggest trade-off: it is built around voice, not music — one ear only, AptX Mono for calls, and no stereo listening.
• Pick TOZO NC9 if your day is music, commuting, gaming and video with noise cancelling on.
• Pick Atheewon Headset V5.4 if your day is calls — trucking, driving, office, remote work — and you want your other ear free.
The NC9 is a proper pair of wireless earbuds, and the spec sheet reads like one. Two earbuds, 10mm dynamic drivers, an OrigX Acoustic 2.0 tuning claim, a 20Hz–20KHz frequency range and 32 ohm impedance. That combination is aimed squarely at people who want bass and clarity in both ears, not a voice-only device.
The headline feature is hybrid active noise cancelling with a stated reduction depth of up to 45dB. That is not a marketing number you ignore — it is the reason to buy this over a plain earbud. There is also a Transparent Mode, which pipes ambient sound back in, so you can hear a platform announcement or traffic without pulling an earbud out. For commuting, open-plan offices and flights, that pair of modes is the whole value proposition.
Calls are handled by six microphones with ENC, so your voice is pulled forward and background noise is pushed down. The app matters here too: 32 EQ options, adjustable bass, adjustable noise-cancelling modes, and a sharing zone where you can publish your own EQ. Touch controls on the buds, Bluetooth 5.3, a 20-metre range and a claimed 60ms latency round it out.
Battery is the other big number. Up to 60 hours total with ANC off, 40 hours with ANC on, and a single charge good for 14 hours (ANC off) or 10 hours (ANC on). The case has an LED display for remaining battery, and a full charge takes about 1.5 hours. IPX8 is the highest water-resistance rating in this comparison — sweat, rain and splashes are covered.
Who should buy it: anyone who wants stereo music, noise cancelling and long battery in a small case. Who should skip it: if you take calls all day and want one ear free, or you need to connect to a desktop PC that has no Bluetooth, the NC9's in-ear, two-bud format will fight you. It ships in a Dusty Pink finish with six ear-tip sizes, which is worth knowing before you commit to the colour.
The Atheewon V5.4 is the opposite tool. It is a single-ear Bluetooth earpiece on a rotating silicone hook, black, 15 grams, with three ear-tip sizes. One ear is covered; the other stays open to the room, the road and the person next to you. If you have ever worn a two-bud set for a ten-hour shift, you already understand why that matters.
Its reason to exist is calls. Dual microphones with ENC and a -42dBV/Pa sensitivity rating are claimed to cancel around 90% of background noise, and it uses AptX Mono for voice. There is a dedicated mute button, plus physical anti-mistouch buttons for answer, hang-up, volume and playback — real buttons, on the device, no app required. Button control is the only control method listed, which for a driver or a trucker is a feature, not a limitation.
Connectivity is where it separates itself. Bluetooth 5.4, a 50-foot stated range, and simultaneous dual-device connection so you can take a laptop call and keep your phone paired at the same time. It also ships with a USB dongle for computers, laptops, tablets and non-Bluetooth devices, across Windows, Mac, Android and iOS. That dongle is the single biggest practical difference: it means you can use this on a work desktop with no Bluetooth radio at all.
Battery is enormous on paper: 115 hours of total playtime from the charging case, with a 1.5-hour charge time and an LED screen on the case to show remaining power. Atheewon notes playback varies with volume. Protection is IPX7 — light moisture and sweat, fine indoors or on the move. A two-year warranty is listed.
Who should buy it: drivers, truckers, dispatchers, remote workers, anyone on calls most of the day. Who should skip it: if you want to listen to music in stereo, watch films, or use noise cancelling while commuting, this is the wrong device. Mono voice is the point; stereo music is not.
• Best for noise cancelling → TOZO NC9. Up to 45dB hybrid ANC with a Transparent Mode; the Atheewon only lists active noise cancellation on the mic side for calls.
• Best for music and media → TOZO NC9. Two earbuds, 10mm dynamic drivers, 20Hz–20KHz, 32 EQ options, 60ms latency for games and video.
• Best for long call shifts → Atheewon Headset V5.4. Single-ear hook, dedicated mute button, dual-mic ENC, AptX Mono.
• Best for battery life → Atheewon Headset V5.4 on the headline figure (up to 115 hours total), though both charge in about 1.5 hours.
• Best for computers without Bluetooth → Atheewon Headset V5.4. The included USB dongle covers Windows, Mac, Android and iOS; the NC9 is Bluetooth-only.
• Best for water resistance → TOZO NC9. IPX8 versus IPX7.
• Best for two devices at once → Atheewon Headset V5.4 with simultaneous dual-device connection and a 50-foot range.
• Best all-rounder for a commuter → TOZO NC9. ANC, Transparent Mode, six ear-tip sizes and a case with a battery display.
• Best for one-ear freedom → Atheewon Headset V5.4. Rotating hook, 15g, three tip sizes.
In my opinion, most people shopping this comparison should buy the TOZO NC9. It does more jobs: music, calls, gaming, commuting, noise cancelling, water resistance, app tuning. It is the one device that covers a whole day rather than one task.
I would only point you to the Atheewon Headset V5.4 if calls are genuinely your priority — especially if you drive, work a desk phone or a Bluetooth-less PC, or need one ear open at all times. If that describes you, the dongle, the mute button and the single-ear hook are worth more than stereo sound. Check the current price on Amazon before deciding, since the two sit in different categories of device and the gap matters more than any spec on this page.
Not necessarily. The NC9 has six mics and ENC for clear calls, but the Atheewon is purpose-built for voice — dual mics, a -42dBV/Pa sensitivity rating, AptX Mono and a physical mute button. For back-to-back calls I would pick the Atheewon.
The Atheewon lists up to 115 hours of total playtime; the NC9 lists up to 60 hours with ANC off and 40 hours with ANC on. Both charge in roughly 1.5 hours.
Yes — that is what the included USB dongle is for. It supports Windows, Mac, Android and iOS, and the headset also pairs with two devices at once over Bluetooth 5.4.
It lists 60ms audio latency and Bluetooth 5.3, and the description mentions minimised delay and precise sound sync. For low-latency stereo media, the NC9 is the one of the two built for it — the Atheewon is mono and voice-focused.
